'Myinvention has reference to 'water andother liquid meters, inwhich two or more reciprocating pistous are used, both of'which are connected with` one andthe saine vcrank-shaft, and" which are made to operate 'valves for the purpose of controlling the lpistons.

-The `invention consists in a certain construction of th'e valves and arrangement of the passages controlled by them, whereby a balancing character-or action is secured forthe valves, and an ecient operati-on otA themeter generally obtained under. both light and heavy streams; also, acheap and simple construction pfmeter produced.

l Referring to the accompanying drawing- TA and A represent two vertical cylinders or meas- 'inning-chambers, open at their cndsandarranged with-4 in a water-box or case-,3, byfitting them through horiz'ontalrbs b b, which, in conjunction with vertical `partitions c c, serve to establish upper and lower scp- -:irate water-spaces or chambers O D C D', and an intermediate space, E, all surrounding or being on the Y' Aoutside of the cylinders, and the upperand lower of lid spaccscommunicating' respectively with thetop and bottom ends of the cylinders, but the intermediate space E not being in direct communication'therewith, and having connected with it the exhaust-pipe or out- 'The ribs b b are `disposed iutermedately ofthe .l length ofthe cylinders, or at a suitable distance from their ends to form said spaces or chambers.

F F' are the reciprocating pistons ofthe cylinders A'. These pistons are connected, by pitmen e c', with' cranks ff' of a single-upper'horizontal shaft, G, ar-

on either -side of the chamber H for the cranks ff to' revolve in.

The top J has also arranged within it a space, g,

for the registering mechanism, which maybe operated by a screw and worm-wheel from 4the main shaft, or otherwise.

The water enters the meter through the chamber Il by an inlet, 71, andis passed from thence, alternately', to the opposite sides of the pist-ons, as required, by means of valves K K', operated by beams 'ii' arranged within the chamber H, and receiving their motion from crank.' or ,eccentric pins l; k' connected with the shaft fG. A

These valves K K', which, 'by the devices just de-4 scribed, have a vertical sliding action communicated .to them, are of an irregular cylindrical shape, .being formed with piston-heads at their opposite ends and a 'reduced body-portion in between, thereby giving to them a reel-shape.

Said valves aremade tubular, having a llongitudinal passage, Z or Z-, through them, and playthat is, their piston-heads or ends-within upper and lowercylin inders or boxes, L 'M and L M', open at their ends tothe exhaust space or chamber E, and the upper ones L L' open also to the inlet-chamber H, while the lower ones M M' are open below with a communicating passageTHC t'o freely circulate through the valves, and the latter have a balance character or action secured to them.

Communication is established by these valves alter- .nately at their opposite ends, between the chambers C D G' D' and exhaust-chamber E, to keep up a reciprocating action of the pistons by means of ports, m n, and m"'n.', made in or through the cylinders L M and L' M', and communicating with the chambers C D and O D, over which ports the piston-heads of the valves play to control the movements of the pistons.

What isl here claimed, and desired to be secured by Letters Patent, is-

lhe combination` of -the tubular' slide-valves K K', formed with a piston-head a'teither end of them, the cylinders or boxes L M and L' Ml with their ports m. n lm. n', the chambers oi" passages H H O D C' D', the exhaust-chamber or passage E, and the cylinders A A with their pistons F F', for operation in concert with or through` a crankshaft, G, substantially as specified.
